First, Gecko is not being told to do a "view-source" operation (which is a regression). Second, the URL we're being given is wrong; in each case we're told to load about:blank. Third, this operation results in a crash. I'd call this a major regression. View source is used by lots of folks for all kinds of testing.
This is, I belive, a dup of another "view source" bug that was fixed by mscott. I'm marking this FIXED.
Adding verifyme keyword.
not a problem for me. verif using opt comm bits  on linux, winNT and mac.
